Description This setpoint adjusts the threshold level for the generator overvoltage shutdown
protection. The threshold is adjusted in % of the nominal generator voltage, which
is either
BankNomV or BankNomVph-ph , depending on the position of the
setpoint FixVoltProtSel .
The protection activates if the voltage in at least one phase gets over the
threshold for time longer than
Bank V del .

The asociated protection to this setpoint is Shutdown type. There is also Breaker
open and cool down (BOC) overvoltage protection, which is adjusted by setpoint
Bank >BOC . The BOC overvoltage protection is intended to be used as first
level protection with lower threshold, whereas the shutdown one is intended
as second level with higher threshold.

Description The setpoint adjusts the delay for generator under- and overvoltage protections.
The thresholds for these protections are adjusted by setpoints
Bank >V BOC ,
Bank <V BOC and Gen >V Sd .

Although the resolution of this setpoint is 0.01s, in fact the adjusted delay is
rounded to the next higher multiple of the period of the generator voltage. The
period is either 0.02s for 50Hz systems or 0.0166s for 60Hz systems. E.g. if the
delay is set to 0.03s at 50Hz system the real delay will be 0.04s.
